What to Focus On
- Insolation is the incoming solar radiation received by Earth.
- It is measured in short waves.
- Only a small fraction of the Sun’s total energy reaches Earth.
- Higher angle of incidence = more concentrated heat.
- Longer daylight = more insolation received.
- Clouds, dust, and water vapor reduce insolation by reflection and absorption.
- Radiation is the primary method of energy transfer from the Sun to Earth.
- Terrestrial radiation (long waves) heats the atmosphere more than insolation.
- Conduction affects only the air in direct contact with the ground.
Common Mistakes to Avoid
The Sun directly heats the atmosphere, so the air should be hotter closer to the Sun (i.e., higher up).
Insolation is the same as temperature; more insolation always means higher temperature.
The Earth receives most of the Sun's energy.
Memory Tips
Insolation means incoming solar radiation.
Four processes of atmospheric heating: Radiation, Conduction, Convection, Advection.
Angle of incidence affects insolation intensity.
Transparency of atmosphere affects insolation – clouds, dust, water vapour reduce it.
